3D printing is an emerging technology that is revolutionizing the manufacturing industry in many sectors, including aerospace, automotive, medical, and design. The nautical industry is beginning to experiment with the use of 3D printing for the production of components and parts for boats. This innovative technology offers a range of advantages over traditional production methods, such as the ability to create highly customized, lightweight, and durable components using an automated and highly efficient production process. Additive manufacturing offers a range of unique benefits for the nautical sector, including the ability to produce highly customized, lightweight, and durable parts and components. Thanks to its flexibility and the ability to create complex shapes, 3D printing allows for the production of specific parts and components for each boat, reducing the need to stock expensive spare parts. Moreover, AM production systems allow for the creation of lightweight and durable components using innovative materials, such as fiber-reinforced composites, which offer greater strength and lightness compared to traditional materials. This factor can significantly contribute to reducing the weight of the boat and improving performance in terms of speed, maneuverability, and fuel consumption. Another advantage of additive manufacturing is the ability to produce parts and components in a fully automated manner: this can help reduce production times and costs associated with the production of parts and components, offering a significant competitive advantage for boat manufacturers. Despite the advantages of 3D printing in the nautical sector, there are also some challenges to consider in using this technology. One of the main challenges is the need to ensure the quality and safety of the components produced with 3D printing; since the components are produced automatically, it is necessary to ensure that they meet the quality and safety standards required by the nautical sector, which is not entirely negligible when compared to the composite materials widely used today. Furthermore, being a relatively young production process, additive manufacturing requires specialized knowledge of materials and production processes, which can be a challenge for boat manufacturers who lack experience in this field. For the same reasons, technically advanced technologies still have prohibitive costs compared to the actual benefits offered: the investment in specialized equipment for the production of boats (or parts thereof) in AM can therefore represent a challenging barrier to entry. In the continuation of this discussion, we will explore the reasons why 3D printing can be considered one of the new frontiers of the nautical sector, highlighting the advantages and challenges of using this technology in the production of boats and their components. The research focused on analyzing the state of the art of AM applications in the nautical sector, with the aim of identifying the main direction for the dissemination of this technology within the industry. Lacking sufficient mechanical skills or practical experience, it was decided to use commercial machinery and technologies currently available on the market, also to accelerate the practical results of the research as much as possible. The study of new decomposition techniques, the design of the direction and printing parameters to be used for each component, the analysis, and development of assembly techniques were therefore the basis of the method through which the candidate contributed to the realization of various projects, developed almost entirely in collaboration with the company Superfici, which made its laboratories and machinery available. The results obtained represent demonstrative case studies, aimed at proving the actual potential of the technology and its applications in the nautical and industrial sectors. The theme of developing new machinery, capable of responding more to the needs of the industrial and nautical sectors, although outside the scope of this discussion, is of considerable interest and leaves room for various scenarios for future research into this topic.
La stampa 3D è una tecnologia emergente che sta rivoluzionando l'industria manifatturiera in molti settori, tra cui l'aerospaziale, l'automotive, il medicale e il design. L'industria nautica sta iniziando a sperimentare l'utilizzo della stampa 3D per la produzione di componenti e parti per imbarcazioni. Questa tecnologia innovativa offre una serie di vantaggi rispetto ai metodi di produzione tradizionali, come la possibilità di creare componenti altamente personalizzati, leggeri e resistenti utilizzando un processo di produzione automatizzato e altamente efficiente. La manifattura additiva offre una serie di vantaggi unici per il settore nautico, tra cui la possibilità di produrre parti e componenti altamente personalizzati, leggeri e resistenti. Grazie alla sua flessibilità e alla capacità di creare forme complesse, la stampa 3D consente di produrre parti e componenti specifici per ogni imbarcazione, riducendo la necessità di tenere in magazzino parti di ricambio costose. Inoltre, i sistemi di produzione AM consentono di creare componenti leggeri e resistenti utilizzando materiali innovativi, come i compositi rinforzati con fibre, che offrono una maggiore resistenza e leggerezza rispetto ai materiali tradizionali. Questo fattore può contribuire in maniera significativa a ridurre il peso dell'imbarcazione e migliorare le prestazioni in termini di velocità, manovrabilità e consumo di carburante. Un altro vantaggio della manifattura additiva è la possibilità di produrre parti e componenti in modo completamente automatizzato: questo può contribuire a ridurre i tempi di produzione e i costi associati alla produzione di parti e componenti, offrendo un notevole vantaggio competitivo per i produttori di imbarcazioni. Nonostante i vantaggi della stampa 3D nel settore nautico, ci sono anche alcune sfide da considerare nell'utilizzo di questa tecnologia. Una delle principali sfide è la necessità di garantire la qualità e la sicurezza dei componenti prodotti con la stampa 3D; dato che i componenti sono prodotti in modo automatizzato, è necessario garantire che rispettino gli standard di qualità e sicurezza richiesti dal comparto nautico, elemento non del tutto trascurabile quando si pensa al confronto con i materiali compositi oggi largamente impiegati. Inoltre, essendo un processo di realizzazione relativamente giovane, la manifattura additiva richiede una conoscenza specializzata di materiali e processi di produzione, che può rappresentare una sfida per i produttori di imbarcazioni che non hanno esperienza in questo campo. Per gli stessi motivi, le tecnologie tecnicamente più avanzate risultano avere costi ancora proibitivi, paragonati agli effettivi vantaggi offerti: l’investimento in attrezzature specializzate per la realizzazione di imbarcazioni (o parti di esse) in AM può pertanto rappresentare una barriera d’ingresso difficilmente arginabile. Nel proseguo di questa trattazione, esploreremo i motivi per cui la stampa 3D può essere considerata una delle nuove frontiere del settore nautico, evidenziando i vantaggi e le sfide dell'utilizzo di questa tecnologia nella produzione di imbarcazioni e di sue componenti. La ricerca si è concentrata sull’analisi dello stato dell’arte delle applicazioni di AM nel settore nautico, con l’intento di individuare la direzione maestra per la diffusione di questa tecnologia all’interno del comparto. Non avendo a disposizione sufficienti competenze meccaniche né esperienza pratica, si è deciso di avvalersi di macchinari e tecnologie commerciali attualmente presenti sul mercato, al fine anche di accelerare il più possibile i risultati pratici della ricerca. Lo studio di nuove tecniche di scomposizione, la progettazione della direzione e dei parametri di stampa da impiegare per ciascun componente, l’analisi e lo sviluppo di tecniche di montaggio sono quindi stati alla base del metodo attraverso il quale il candidato ha contribuito alla realizzazione di diversi progetti, sviluppati quasi interamente in collaborazione con l’azienda Superfici, che ha reso disponibili i propri laboratori e macchinari. I risultati ottenuti rappresentano dei casi studio dimostrativi, il cui obiettivo è quello di dar prova delle effettive potenzialità della tecnologia e delle sue applicazioni nel comparto nautico e industriale. Il tema dello sviluppo di nuovi macchinari, in grado di rispondere maggiormente alle necessità del reparto industrial e nautico, sebbene esuli dalla presente trattazione, risulta di notevole interesse e lascia spazio a diversi scenari di futuro approfondimento di questa ricerca.
